Variables in PHP are local to functions unless explicitly
declared global via the "global" statement.

There are a few exceptions, called "superglobals", such as $_POST,
$_GET, $_SERVER, $GLOBALS, etc., which are global in every
scope.  But other than those, a variable is local to a function
unless declared global.
